Abstract

The invention discloses a pressure sensor for water pumps and a detection data compensation method thereof, and aims to provide a pressure sensor for water pumps which can adapt to temperature change,has high sealing performance and is reliable in detection. According to the technical scheme, the pressure sensor includes a housing, a pressure detection device installed in the housing, and a rearcover screwed to the rear end of the housing; an inner convex ring is arranged in the housing; the housing is provided with a through hole communicated with the inside of the housing; the inner convexring is sleeved with an annular insulator; a sealing ring is abutted between the insulator and the inner convex ring; the insulator is used for sealing the end of the through hole near the inside ofthe housing; and the pressure detection device is installed on the side of the insulator away from the through hole. The pressure sensor is suitable for being used on a water pump to detect the waterpressure of the water pump.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a pressure sensor for a water pump. Background technique [0002] The water pressure in the pump body needs to be collected on the water pump, and it is a relatively popular method to use a pressure sensor for detection. There are many types of existing pressure sensors. [0003] Conventionally, various pressure sensors have been proposed in which a pressure detection element is accommodated in a pressure detection chamber, and the pressure applied to the pressure detection chamber from the outside is transmitted to the pressure detection element, thereby outputting a voltage signal corresponding to the external pressure from the pressure detection element. . [0004] For example: Chinese patent application number 201210321001.7 discloses a water pump pressure sensor, including a housing, an elastic diaphragm, a magnetic core, an inductive coil, a spring, an inductive ...
